Frontiers Lecture: How to Take a Picture of a Black Hole

Black holes are the most exotic objects thought to exist in the universe, but no one has ever seen one. In this podcast, Shep Doeleman, scientist and Assistant Director of the Haystack Observatory at MIT, will explore the evidence for black holes, and describe an effort to link radio dishes around the world to form an Earth-sized virtual telescope that will make the first images of the supermassive black hole at the center of the Milky Way.
